DAVID RENSHAW, OF BOSTON, MASSACHUSETTS, ASSIGNOR or ONE-THIRD TO EDWARDLALLY', OF SAME PLACE.

SPRING BED-BOTTOM.

SPECIFICATION forming" part of Letters Patent No. 271,517, dated January30, 1883.

Application filed December 26, 1882. (No model.)

To all whom 2t may concern:

Be it known that I, DAVID RENSHAW, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Spring Bed-Bottolns;

and I do hereby declare that the following is a full. clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertaii'is to make and use the same, reference beingbad to the accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

My invention relates to certain new and useful improvements in springsespecially designed for use in connection with the ordinary slats ofbedsteads to form a spring bed-bottom; and the invention consists innovel features of construction and combination and arrangement of parts,as will be hereinafter fully (lescrihed, and specifically designated inthe claims. Y

In the drawings, Figure l is a top or plan view of my improvedbed-bottom. Fig.2 is a transverse section thereof; Fig. 3, a detachedview of the spring.

The letter A designates the slats of the bedbottom, and B the springs.These springs are formed of pieces or strips of the best steel or brass,bent in the shape as shown in Fig. 2, and connected transversely fromone slat to another, the ends being turned under the slat, as shown atb, and nailed, screwed, riveted, or otherwise secured thereto. A strip,G, is nailed to the bottom of the slats at each end, which Serves as abrace to the same and prevents them from wabbling. The slat at themiddle of the bed-bottom is divided longitudinally, as shown, and thetwo parts hinged together at each end or in the center thereof, asindicated by the letters 0 c, which .enables the two halves of the bedto be folded back to back for transportation; or it can be so hinged atits middle portion to fold up top to top, as the Springs are so arrangedto enable this to be done quite as readily as the other way. Forinstance, a row of springs being fastened along the slats, as described,the next row is so arranged as to bring them either to the right or theleft of the former row, making them come between the same, and when thetwo halves of the bed are folded the springs, by being so arranged, willfit in the spaces thus created. The springs can be made of strips ofsteel, brass, or any material that is sufficiently elastic, from one tothree inches wide, according to circumstances and bent in any suitablemanner and by any suitable means.

A spring bed-bottom of this construction is particularly adapted to easeand comfort, the 6c springs all being of the same height and of the sameelasticity, and hollowness or sinking down of any part of the bedavoided while 1ying thereon. Numbers of beds are already in 1 use toobviate these defects; but they do not 6 accomplish theobjectso well asin this instance.

The advantages of this form of spring-ale simplicity of construction,cheapness of first cost, and durability. They can be made by dies inmuch less time than is now consumed in making-springs for the samepurpose, and they are so formed as to pack in small space in packagesfor commercial use and tor transpor; tation. Furthern'ime, these springscan be ap-- plied to any ordinary bed-slats by any person, but littleingenuity being necessary to fasten them between the slats, as shown,and the strips 0 0 applied or not, as may be desired.

\Vhat I claim is- .1. In a spring bed-bottom, the slats A, secured t0the transverse strips U C, and being connected by the series of springsB, formed substantially as shown, and secured to the slats on the bottomthereof, said bed-bottom being hinged at its middle portion, whereby itcan be folded together for transportation, substantially as specified.

2. As a new article of manufacture, a bedspring formed substantially asand in the manner set forth.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presence of two witnesses.

DAVID RENSHAVV.
